Contractors Listening to Our Customers: Why We Created the Lockable Interlock Kit
At Interlock Kit, we’re always listening to our customers — and one of the most common questions we get is: “Can I lock out the interlock kit to prevent others from turning on the breaker?” Until now, there hasn’t been a simple, cost-effective way to do that. That’s why we’re excited to announce our new Lockable Interlock Kit, designed to give homeowners, electricians, and facility managers a reliable way to secure their generator interlock kits in specific positions. This new hasp-style design allows users to safely lock the breaker handle in place using a standard padlock or combination lock, preventing unauthorized operation and enhancing overall safety.
Simple, Effective Lockout for Any Power Setup
The Lockable Interlock Kit was created for those who want an added layer of protection without complicating their setup. Whether you’re ensuring compliance on a job site or preventing accidental backfeeding during maintenance, this system offers a simple, effective solution. It installs just like our standard interlock kits but includes a precision-machined slot that allows a lock to be attached directly to the plate. Once locked, the breaker handle cannot be moved—providing a clear and physical lockout that keeps your power system secure.
Built for Strength, Durability, and Longevity
Built with the same durability and precision that our customers expect, the Lockable Interlock Kit is manufactured from high-grade stainless steel for long-lasting performance. The design is compact, corrosion-resistant, and built to handle real-world conditions in both residential and commercial environments. Like all of our products, it’s engineered for strength, reliability, and a clean professional appearance that matches your existing panel hardware. This new model is part of our KL-line, created to complement our solar KS-line—offering customers a complete range of interlock solutions for both standard and solar applications.
A Smarter Alternative to Traditional Lockout Systems
When compared to more complex lockout systems like Kirk Key, our new lockable design offers the same level of safety and control in a much simpler and more affordable package. Unlike Kirk Key systems that require multiple locks or interlocking points across several breakers, our Lockable Interlock Kit allows you to secure the breaker directly at the panel with a two locking points. This provides a clear, reliable way to prevent operation without the need for special tools, wiring modifications, or multiple key systems. It’s a practical, easy-to-use solution for residential, commercial, and industrial applications—anywhere you need added control and security over your power system while keeping installation straightforward.
